TRI-PLEX

Tube box courtesy of Damon Limeback.

Tri-plex was a Canadian tube company. They were either a washhouse or a re-brander. I'm not sure. AGS stands for American General Supply (of Canada), Ltd. Says so on the box. They were headquartered in Montreal, Quebec. It may sound strange saying American Supply of Canada, but remember, anyone from South, Central or North America is technically American. Just here in the US we tend to use it to refer to ourselves exclusively.
